How do I delete desktoppicture.db?
I have been experiencing the issue where the desktop wallpaper reverts on reboot. I tried every fix I could find online (Mission Control, etc.), but, I believe I have narrowed down the issue to a corrupt file.
A look at the desktoppicture.db file in ~/Library/Application Support/Dock shows the file is empty. Cross referencing with another Mac, I believe this file is the issue, however I am unable to delete or modify the file.
I have tried deleting, overwriting with a working file, renaming, disabling SIP, using terminal (rm, sudo rm, sudo rm -R, etc.) to no avail. I'm still thwarted by the "Permission denied" error, even after entering my password.
Does anyone have any suggestions on how else I might try deleting/replacing this file?
